Why do larger trucks have some wheel rims that extend out more than the other rims?

Are you asking about rims like [this](https://static.wikia.nocookie.net/ford/images/e/e1/2021FordE-450.jpg/revision/latest?cb=20210315101756)?
The front rim appears to stick out farther than the rear, but it’s actually identical. The rear axle has two wheels on each side, with the inner one oriented the same direction as the front (with the rim sticking out farther than the tire) and the outer one reversed (with the rim sticking in towards the other rim). This way, both of these rims are attached to the axle on one set of bolts with the rims touching each other. The rim on the front axle is shaped this way so that it is identical to the rim on the rear axle (i.e. only one spare is needed).
